- T o all whom t may concern.'

Be it'known that I, BENJAMIN D. CHAM- BERLIN, a citizen of the UnitedStates of America, and a resident of Washington,

District of Columbia, have invented certain new and useful Improvementsin Apparatus for Gathering Glass and the Treatment Thereof onBlowpi'pes, of which the following is a '.speciication. v

This invention has for its object Ito perform by machinery allmanipulations of the blow-pipe iron, now generally. performed.

by hand, from' and including the time the same is insertedv in the potto gather the glass -thereon to and'including the time the blow-pipewith the glass thereon is placed in position -to be enclosed within themold.

4In the precise construction of the machine shown herein, the blow-pipeis. presented device or chuck and mechanism is provide for efblow-pipe,for the purpose of elcngating and shaping 'the article upon theblow-pipe, resent vthe blowipe to vtheV e blowing, parts having suchintermit-l tent-action as t turn of thec'huck towards'the pot, theAhlow-- 'pipe being-removed 'from the chuck during vthe time 1t ispresented at' its blowing' poul- F ig: 5. 'llig. 7 is a central view ofthe blow-pipe l in the pot or furnace opening, to move it in a verticalplane, so that gathered glass is presentedto the marvering device and toswing it upon the vertical plane axis for the pur ose of elongatinv' andshaping the gathere glass and finally to present it at the blowingposition. The swinging .mechanism for the blow-pipe aswell as thetraversing mechanism for the blow-pipe chuck are intermittent in theiraction in that they have positions of rest corresponding to thegathering and blowing posltlons and to a posi` tion (marvering)intermediate thereof. It further embodies suitable marvering mechanismand means whereby the several mechanisms above referred to are broughtinto and maintained in synchronism with each other and are lcaused toproperly and successively perform the operations for which they aredesigned.

The base of the machine comprises a suitable wheeled frame 1 adapted tobe secured in a fixed position in respect to a blowing mechanism A ofthe general character described in my other application S. N. 589,786hereinbefore referred toand to be maintained in a fixed position inrespect thereto.

The wheeled frame has on that end thereof opposite to the end to whichthe blowing mechanism is secured and on each side ot its longitudinalaxis, an 'up-standing skeleton frame 2 having a circular bearing 3projecting from the top centerA thereof inwardly. On each of thebearings 3 is mounted a hub 4a of radius arm 4. As the several partswhich are mounted on or coacting with the radius arms are in duplicate,one for each side of the frame and are similar, I will for convenienceconne the following description to one set of them. The outer end of theradiusarm has a hu 4b in which is mounted a sleeve 5a on the projectinginner end of which is keyed the hub 5b on one end of an outer arm 5, theopposite end of which arm is formed into a hub 5 to support theblow-pipe receiving mechanism or chuck. The lower` end 4 of t-heradiusarm is continueddownwardly and bent in wardly w'here it is formed into asegmental rack 6 located above a corresponding segmental rack 7 ofgreater radius carried by theskeleton frame, a pinion -8 beinginterposed between the two segmental racks and aving a motionlongitudinally of themachine im arted thereto by means of mechanismwhlch will be hereinafter described, whereby the radius arm will becaused to arm bearing companied by proper periods 'of rest.

Swingin an arc of a circle around the radius 3. As before stated theouter arm 5 is keyed to one end of the sleeve 5 mounted in the upper endof the radius arm 4 and the oppo site end of the said. sleeve-projectsto the lfront of the radius arm and has keyed thereon 'a pinion9 whichmeshes with a segmental rack 9a the-ends 9" of which extendlongitudinally of the machine and are carried by parallel links 10pivoted to the skeleton frame symmetrically in respect to the axis ofmovement of the radius arm, a suitable curved guide 9 being carriedbythe outer face of the radius arm to maintain the rack in engagementwith the said pinion. Owing to this constructionthe swing of the radiusarm about its sleeve will be accompanied by a change in the meshingposition of the'actuating pinion 9 for the outer-4 arm and its segmentalraek, whereby as the radius arm is swung to either side ofa `verticalline, the outer arm will be given a further movement around its sleeveand swung in respect to the said radius arm, the vrelation between theradius arm andthe outer arm in the extreme positions of the former beingsuch that the latter is projected towards 'the furnace or towards theblowing machine according to whether the radius arm is to one or theother side of its vertical position.

The pinion 8 interposed between the two segmental racks 6 and 7 ismounted on the link 11 from a longitudinally movable slide 12 guided inbrackets 12 from the inside of the skeleton frame and having motionimparted thereto by a stud 12b thereon engaging a cam track 13 in theperiphery of the drum 14 constantly driven by mechanism to behereinafter described and carried in bearings 14* in the skeleton frame.The track is so shaped that while parts of it 13b,- 13'1 and 13' extendspirally of the periphery of the drum, thereby im arting motion to theslide longitudinally oi) the base through the intervention of the pinionand segmental properly time the blow-pipe in respect 'to the blow aparatus.- The swinging motions of the radius arm will as 'beforedescribed effect the swinging motion of the outer arm 5 around the upperends of the radius arms and hence the instrumentalities before described`effect a traversing motion of the blow-pipe chuck between the furnaceand the blowing devices, such motion being ac ositions of restcorrespond- The blow-pipe receiving mechanism consists` of afcy indricalbodyl ljhaving a slot in its inner face in .w vich is pivoted by atransverse pivot 15", a air of arms 16 each of which is 'provide withunder-cutjaws 16. The blow-pipes C used ,with this machine have rigidlysecuredthereto a bevelled pinion -17 and adjacent'to the pinion havecollars 17* between which and on the \pipe is mounted a rotatingsle'eve17", one side of which is produced with a projection 17c as shown, theopposite ends of such projecting portionsfbelng notched as atv 17 e andprovided with undercut shoulders 17 adapted to be engaged by theundercut jaws 16a ofthe chuck arms. Sleeved on the chuck body 15 is thehub 18d of the bevelled gear 18, the hub carrying on its opposite andinneren'd, by a splined connection, a second gear 19, such last namedgearbeing capable of movement axially of the chuck, and be.

ing provided with an annular recess 19l in its inner faceinto which atdiametrical op,-

posite points projects fingers 161 onthe ends of the chuck arms.' Eachchuck arm 16 has a corner 16 located on the opposite side of the axis ofthe chuck toits engaging jaw 16a and projecting beyond the faceof thechuck body, so that in inserting the blowpipe into the chuck the facevof the projec tion 17 of thesleeve of the latter .will by contacting.vwith the said corners 16 throw the jaws l16H-of the chuck arms towardsthe blow-` i e,'thus enga ing them with the undercut sl'iouldersl?c othe sleeve 17 b and will simultaneously project the gear 1 9 towardsthepinion 17 on the blow-pipe firmly held in -this position by theundercut jaws and faces. v

v Carried on'the outer arm 5, whichlatter is inclined from itspoint of.attachment with, the radius arm 4 inwardly towards the cen-A ter lineof the machine, is a shaft20, which at its lower. end' has a.' bevelledpinion 2'()a meshing with the vbevelled gear 18 sleevedupon thechuckbody, and at its upper end amitre gear 2G meshing with a correspondingpinion 20 upon the inner endof a cross shaft 20 PaSSiIl "throughthevsleeve 5 of the outer armto t e outer face of sufchsleeve where ithaskeyedthereto a mitre gear .20 meshing with a. corresponding mitrepinion 2Q keyed to a shaft '20 Vcarried upon thev outer face ofthegradius arm 4 in suitable bearings, the ylower end of suchshafthavingkeyed thereon azmitre gearl 20.meshing with acorrespondingpinion 20* carried upon the through thezskeleton frame andcentrally f through the ,arm Y bearing' sleeve 8;

Mountedupon the radius arm vsleeve 3 to the inside ofthe radius arm from whichit is separated byay nut 1")a is a bevelled gear 24 meshing with` thegear 22a on the radius arm shaft, such gear hav-` ing upon vits hub aspur gear 24a engaging with arack 25 guided' in bearingv 25- projectinglfrom the inside of the skeleton frame and-the hub. i Motion is impartedto the rack 25 by a spur gearg26 mounted on .the inner'end of atransverse shaft 26, the and cause the two to mesh, the parts being souter end ofsuch shaft having a spur. gear 26b meshing with a rack upona vertical slide 27 which carries a stud 27a taking' into a cam track28-upon theend of the drain The function of operation to be per. formedby this'c'amtrack will be hereinafter described.

This shaft isdriven by an appropriate mechanism to. be hereinafter referred to.

Mounted in the base frame of the machine to one side thereof is asuitable main drive 31 (shown in dotted lines in Fig. 1), such as anelectric motor, the shaft 31a V of which carries a worm'31b meshing witha worm 31 on the vertical driving shaft 29 of the marverer. The mainshaft 31 of the motor further carries pinion 31d driven through an idler31, a pinion mounted on the lower transverse shaft 31t of the machinewhich latter shaft carries on each end a worm 318, each of which engagesa worm wheel 31h fast upon the end ofthe actuating drum 14 of thecorresponding arm whereby translating motion of the chuck is effected.Such transverse shaft moreover carries thereon on each side of itscenter a sprocket -'wheel 31 from each of which through the interventionof sprocket chains 31 motion is transmitted to the sprocket wheel 20mcarried on the inner ends of the shaft 2()k from which the blow-pipesare rotated,

I have hereinbefore stated the molding and blowing mechanism which isshown diagrammatically in Figure 1 is of the character shown in my otherapplication, Serial Number 445,252, filed `July 24, 1908, renewed onOctober 29, 1910, as Serial Number 589,786. As shown in Figure 15 of thepresent drawings (which figure is a copy of Figure 3. of the drawings inthe last named case) such mechanism com rises a base D supporting avertical tubu ar standard D, in which is contained the vertical drivingshaft E, driven through bevel gears F and F and a clutch G by a motor H.The clutch G is of such a character that it releases itself afterdriving the shaft E through a complete l revolution, and is adapted to'be thrown into engagement to start the rotation of the shaft by meansof a yoke g, formed upon the rearwardly extending end of a lever g whichis pivoted near its upper end on the standard, and whose upper end isbifurcated to receive the blow-pipe C, the weight of the blow-pipe wheninserted there- 'in actuating the clutch. A cam track H is formed on thelower end of the vertical shaft, and in it .a stud h, connected by linksz. to the pivoted mold halves I,.runs, the arrangement being such thatwith the shaft in its normal position the mold halves are open, andthatduring the rotation of the shaft they are'clos'ed andso held for aproper period before being opened.

On the up er end ofthe standard is the air, head l, t e air valve 1h ofwhich is actuated' at about the time the mold isclosed, through therotation of the shaft, to admit blowing air.

In the operation of the device an arm 5 being in the position shown inthe left of Fig. 1, the radius arm 4 will by the rotation of the camcylinder 14 be swung to the right about its sleeve 3 and in thismovement the outer arm 5 will swing about its pivot on the outer end ofthe radius arm downwardly and toward the right, decreasing the anglebetween it and the radius arm. During this movement in order to clearthe mouth of the furnace or j time being lifted by the inclined portion28al l of the cam track 28 on the end of the cam cylinder 14. Thecontinued rotation of the drum swings the radius arm and 'the outer armfrom the position in which the blowpipe will clear the ot or furnace toa position in which the blow-pipe chuck will be over the marverer, thisbeing effected by the swinging of the radius arm around its sleeve andthe swinging of the outer arm upon the radius arm; This will also beaccompanied by a swinging of the blowpipe-in a vertical plane around theaxis of the chuck so thatat the time the chuck is above the marverer thegathering end of the blow-pipe will be hanging vertically from thechuck, which ma be effected with a concentric run 28" of tlyie track 28by a proper proportioning of the gearin s- 24, 22, 22, 23, 21, 21g' and21. swing reached the marvering position referred to,

the motion of the radius arm and the outer arm is arrested by reason ofthe fact that the stud 12" at this time is enga ing the marverinY run 13of the periphera groove of the cylinder, the marvering rollers being sotimed in respect to the arm that at the time the glass upon theblow-pipev is presentedbetween them, their surfaces are` shaping theglass and finally the movement of the radius arm and outer arm are re-"sumed by the cam run 13l and the chuck is positioned with respect totheblowin apparatus, the run 28d being so shaped that at this instant theblow-pipe is vertical and is stationary at this time. The motion of theradius arm and outer arm is also arrested by the fact that the actuatingslide v rotated towards the furnace, which is effected by the return run13? of the peripheral cam, the chuck being rotated by the run 28" of theend cam. In swinging back towards the furnace the chuck from which.

the blow-pipe has been removed passes the lblow-pipe carried by theother arm which is going toward the blowing machine, but as there is noblow-pipe at this time upon the arm travelling from the blowing machinethey clear each other. After passage of the empty chuck past theloadedone an 'attendant inserts a blow-pipe into such empty chuck in themanner before described and by a continued movement of the radius armand outer. arm the blow-pipe is presented horizontally into the mouth ofthe furnace and then dropped by the inclined run 28t of the .end camtherein to assume the position shown in the left of `I" ig. 1. It willbe noted that this return movement of the arms from the blowing to thegathering position is uninterrupted and that when the blowipe has beenproperly presented into the urnace its translating' movement is arrestedby the actuating slide engaging the gathering run 13a of the peripheralcam track, while after the blowpipe has been dropped into the glass suchmovement is arrested by its actuating stud engaging the concentric run28S of the end dius What I claim and desire to secure by Letv tersPatent isz- 1.
